I didn't think that the GET methods have sockets that needed to be closed.
-What does the send (null) function do?
-Why is it needed?
-When would you purposefully not use it?
If you can, please provide an authoritative link to your source. Surprisingly, I have had trouble finding good explanations for the methods associated with the XMLHttpRequest.
BONUS: In "XMLHttpRequest", How come XML is in caps but Http is not? It's very annoying.
